tests: Add tests for virtual screen cast source
Tests that creating and starting a virtual screen cast monitor works, and that at least one one buffer is processed. Currently the content of the buffer isn't checked more than it can be mmap():ed. Only MemFd buffers are tested for for now, as DMA buffers would need a surfaceless EGL context to check properly. Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1698>
